Quick answer: Yes, you can correct or update your Aadhaar details at a post office. India Post runs 13,352 Aadhaar enrolment and update centres in designated post offices across India. Fees are the same as at any Aadhaar centre. New enrolment is free, a separate demographic update costs ₹75 and a biometric update costs ₹125, with free updates for children in certain age groups. India Post Payments Bank (IPPB) also offers doorstep mobile-number updates for ₹75 and free enrolment of children under five, at selected post offices.
What you can do at a post office Aadhaar centre
India Post’s Aadhaar page lists the following services at its Aadhaar Enrolment cum Updation Centres:
- New Aadhaar enrolment: Your demographic details and biometrics are captured. Enrolment is free.
- Demographic update: Name, address, date of birth, gender, mobile number and email address.
- Biometric update: Photograph, fingerprints and iris scan.
- Document update: Submitting a fresh proof of identity and proof of address.
Some details, such as name, date of birth, gender and biometrics, can only be changed in person, at a post office or another Aadhaar centre. Address and document updates can also be done online, as explained below.
Fees at post office Aadhaar centres
India Post charges the fees set by the Unique Identification Authority of India (UIDAI). All charges include GST.
| Service | Fee |
|---|---|
| New Aadhaar enrolment | Free |
| Mandatory biometric update at age 5–7 (first time) | Free |
| Biometric update at age 15–17 (first or second time) | Free |
| Biometric update between ages 7 and 15 | Free until 30 September 2027, according to UIDAI |
| Biometric update in other cases | ₹125 |
| Demographic update done along with a biometric update | Free |
| Demographic update on its own (name, address, date of birth, gender, mobile, email) | ₹75 |
| Document (proof of identity or address) update at the centre | ₹75 |
An earlier version of this article said a centre visit cost ₹25 and that online and postal updates were free. Those are not the current charges, so pay only the amounts above and ask for a receipt. Check the current fees on uidai.gov.in before you go.
IPPB doorstep services: mobile update and child enrolment
India Post Payments Bank (IPPB) is a registrar for UIDAI. It uses a UIDAI app called Child Enrolment Lite Client (CELC), which postmen and Gramin Dak Sevaks carry on handheld devices. According to IPPB, it offers:
- Mobile number update in Aadhaar at your doorstep: ₹75 including taxes. The service is being rolled out in phases and is available at selected post offices only.
- Enrolment of children below five years: Free. Only a proof of relationship document is needed. The child’s photo and a few details are captured, and the parent’s biometrics are used for authentication; the child’s own fingerprints and iris are not taken. This service is also limited to selected post offices.
To ask for these services, contact your postman or the nearest post office, or call IPPB on 155299. Our guide to Aadhaar for children (Baal Aadhaar) explains what happens when the child turns five.
How to update Aadhaar at a post office
- Find a post office that offers Aadhaar services. Not every post office has an Aadhaar centre. Use UIDAI’s centre locator, which you can filter by service, or India Post’s list of Aadhaar centres. Our guide on finding an Aadhaar centre near you shows how.
- Carry original documents that support the change, such as a proof of address for an address change or a birth certificate for a date-of-birth correction. Take only the documents relevant to the change. The operator scans the originals and hands them back.
- Fill in the update form or give your details to the operator. Check the spelling of your name and address in English and in your local language on the operator’s screen before you confirm.
- Authenticate with your fingerprint or iris and pay the fee.
- Keep the acknowledgement slip. It carries your Update Request Number (URN), which you use to track the request on myAadhaar (myaadhaar.uidai.gov.in) or through the 1947 helpline.
India Post’s Aadhaar page does not mention an appointment system for post office centres. Appointments at bookappointment.uidai.gov.in are for UIDAI-run Aadhaar Seva Kendras; see our appointment guide. For a post office, call or visit first to check its timings and how it issues tokens.
What you can update online instead
An earlier version of this article said you could update most details online with any of several ID documents, or by posting a form to UIDAI in Hyderabad. That is no longer how it works.
- Online on myAadhaar: Only address and document updates can be done fully online. You log in with an OTP sent to your registered mobile number. Document update on myAadhaar is free until 14 June 2027. For address changes, see our guide to updating your address in Aadhaar.
- The Aadhaar app: UIDAI’s Aadhaar app, which is replacing mAadhaar, offers mobile number and address updates.
- Name, date of birth, gender, email and biometrics need a visit to an Aadhaar centre, such as a post office.
- By post: UIDAI’s Citizen’s Charter lists update routes through enrolment centres and the myAadhaar portal. It does not list postal requests, so do not post forms or documents to UIDAI.
How often can you change details, and how long does it take?
- Limits: UIDAI’s Citizen’s Charter says your name can be updated twice, and your date of birth and gender once each. Changes beyond these limits need approval from a UIDAI Regional Office under an exception process.
- Processing time: The Charter says a demographic update is normally completed within 30 days. The original article quoted 90 days.
- New Aadhaar letter: After a change to your name, address, date of birth or gender, UIDAI prints a new Aadhaar letter. Under its Charter it does this normally within 10 days and hands the letter to India Post for delivery. A mobile number or email change does not produce a new letter; you receive a notification instead. Once the update is done, you can also download the updated e-Aadhaar from myAadhaar.
Tips to avoid rejection
The original article’s list of reasons for rejection still applies: wrong or unclear documents, documents that do not support the requested change, and an incorrect mobile number. To avoid them:
- Use a document from UIDAI’s list of acceptable documents that shows the new detail exactly as you want it to appear.
- For a minor, a parent or guardian completes the process.
- Check the operator’s screen carefully before you authenticate, because a typing error means another paid update.
- Keep your URN until the update is complete.

Background: Aadhaar centres in Tamil Nadu post offices (2017)
This article was first written when India Post began offering Aadhaar updates in Tamil Nadu. From 3 July 2017, centres opened at the Chennai head office, Anna Salai, Thiyagarayanagar head office, Mylapore, St Thomas Mount, Teynampet, Anna Nagar, Ashok Nagar and Triplicane post offices. Post office Aadhaar centres now operate across India. That 2017 list may not reflect which Chennai post offices offer Aadhaar services today, so use the centre locator before you visit.
